TOY EUMMINGWHEEL TO ALL WHOM IT MAY CONGERN:

v Be it known that I, W. D. PORTER, of Petersburg, in the countyofDinwiddie, and State of -Virginia, have invented certain new anduseful improvements in Toy Humming-Wheels; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecification, and to -the letters of reference marked thereon, likeletters indicating like parts wherever they occur. A

To enable others skilled in the art to construct and use my invention, Iwill proceedto describe it.

My invention consists in making a new and improved humming-wheel, to beused as a parlor toy, or for amusement'generally. In the drawings-Figure 1 is an edge View,

Figure 2 is a sectional view, and

Figure 3 is a side view. p

In constructing mytoy, I rst cut out two circular pieces of tin or othermet'al, having a diameter of about three inches, and cut four holes inlone of them, near its circumference or outer edge, placing two of themnear each other, and on aline parallel with its circumference, and nearthe opposite ends ofits radii, as shown in fig. 3. These circula-rpieces of tin or other metal I then form into disks A A', iig.` 1,'having. an altitude of about one-twelfth (T15) of their diameter, andunite them in any of the ordinary ways at their edges,-and thus make a.hollow wheel, E, with protruding or convex sides, as shown in figs. 1and 2. Near the centres of the convex sides I fasten two eyes or loops aa` so that they may be about one-quarter orl one-half of -an inch apart.Through these eyes or loops I pass cords B, and fastentheirpoppositeends to wooden handles C, as shown iu tig. 1.

In operating the wheel, I take the handles C C, one in each hand, andthenl whirl the wheel E until it has twisted the cords between it andthe handles tightly together. I then pull the handles in'ioppositedirections,

which causes the wheel to turn rapidly, and, in turning, it getssuliicient momentum to twist the cords in the opposite direction. As itdoes this I move the handles nearervto each other, so that this twistingmay be the more complete. I then pull the handles, as before, inopposite directions, and the wheel turns rapidly, as at first.

. This motion I can keep up for an indefinite length of time. The wheel,as it is revolved in this way, gives out a clear humming noise, to thegreat amusementA and interest of the operator and bystanders.

As a parlor toy, it affords no end of amusement, and serves specially tointerest children, who ca'u operate it as readily as grown people. Itmay be made of different sizes, and with one, two, or more holes groupedtogether in one side, and may be made as ornamentalas desired.

Having thus described my invention, what I claim, is l The toy-.wheel E,formed by the union of twoconcave disks, united at their peripheries,and provided with one or more openings I) and the loops a, when saidparts are constructed and arranged as herein -shown and described.
